[PATCH/RFC] Introduce a built-in attribute "text"

[Michael J Gruber <git@drmicha.warpmail.net>]

"text is the opposite of "binary": It sets the attributes "crlf" and
"diff". It is needed because attribute macros can't be negated,
and some users may want to force git into treating certain files as
text which are not recognized by the internal logic.

This gives the user the chance to mess up completely (given an
"appropriate" setting of autocrlf), but I still think it's a good idea
to have that "-binary" built-in. attributes aren't used by noobs anyways.
In many cases, "diff" might be preferred over "text". Should I add a warning
to the doc?

+Therefore, there is also a built-in attribute macro `text` which allows
+you to mark certain files as text which git does not recognize automatically.
+It is equivalent to setting `crlf diff`.
